Ingingo zibabaza mukumenyekanisha ibinyabiziga bishya byingufu ziracyahari, kandi DC ibirundo byihuta byihuta birashobora guhaza icyifuzo cyo kuzuza ingufu byihuse. Kwamamara kwimodoka nshya zingufu zibujijwe ningingo zibabaza nkubuzima bwa bateri no kwishyuza amaganya. Mu gusubiza ibibazo byavuzwe haruguru, abakora inganda zikomeye bakomeje guteza imbere ikoranabuhanga rya batiri kandi baritabira guhangayikishwa nisoko bashiraho bateri ziyongera. Ariko, kubera ko bigoye kugera ku ntera nini y’ikoranabuhanga mu mikorere ya bateri y’amashanyarazi mu gihe gito, biragoye kugera ku kwiyongera gukomeye muri mileage ku giciro kimwe vuba. Nubwo kwishyiriraho bateri zishobora gukemura ikibazo cyo guhangayikishwa nabaguzi bamwe mugihe gito, ingaruka zacyo nukwiyongera mugihe cyo kwishyuza. Igihe cyo kwishyuza kijyanye nubushobozi bwa bateri nimbaraga zo kwishyuza. Nubushobozi bwa bateri nini, niko urwego rugenda, kandi igihe kinini cyo kwishyurwa kirakenewe nta kongera ingufu zumuriro. Ugereranije n’ibirundo bya AC, ibirundo bya DC byihuta birashobora kwishyuza bateri byihuse, bityo bikagabanya igihe cyo kwishyuza, kunoza imikorere yumuriro, no guhaza ibyifuzo bya banyiri imodoka kugirango byuzuze ingufu byihuse.
Hamwe nimikorere ya DC yihuta yishyuza isimbuza AC gahoro gahoro, OBC yabaye nyamukuru mumasosiyete yimodoka. Kugeza ubu, hari uburyo bubiri bwo kwishyuza ibinyabiziga byamashanyarazi: imwe inyuze ku cyambu cya "yihuta yihuta", ikoresha ikirundo cya DC kugirango yishyure bateri yumuriro; ikindi kinyuze ku cyambu cyo kwishyuza AC, aricyo cyambu cya "gahoro gahoro", gisaba imodoka Nyuma OBC y'imbere ikora transformateur no kuyikosora, isohoka kwishyuza imodoka yamashanyarazi. Ariko, nkuko DC yihuta yo kwishyiriraho ibirindiro buhoro buhoro gusimbuza AC gahoro gahoro, amasosiyete amwe amwe aragerageza guhagarika icyambu cya AC. Kurugero, NIO ET7 yahagaritse icyuma cyo kwishyuza AC, hasigara icyambu kimwe gusa cyo kwishyuza DC hanyuma igatererana OBC. Kurandura OBC birashobora kugabanya uburemere bwibinyabiziga no kugabanya ibiciro byimodoka zikoresha amashanyarazi. Inzira yo guhagarika ibyambu byishyuza AC ntabwo bizagabanya uburemere bwibinyabiziga gusa, ahubwo bizanagabanya ibiciro byihishe nko guhuza ibinyabiziga, ibizamini, hamwe nishoramari ryiterambere ryiterambere, bishobora kurushaho kugabanya igiciro cyo kugurisha ibinyabiziga byamashanyarazi. Byongeye kandi, kubera ko igiciro cyo kubungabunga OBC kiri hejuru cyane ugereranije n’amafaranga yo hanze ya DC yishyuza, guhagarika OBC bizagabanya cyane abaguzi gukoresha imodoka nyuma.
Hano hari inzira ebyiri zo gukoresha ingufu zihuse zo kwishyuza: kwihuta-kwihuta kwihuta hamwe no kwihuta cyane. Mu rwego rwo gukemura ibibazo nkibikorwa remezo byo kwishyuza bidatunganye no kwihuta kwishyurwa, igisubizo cya tekiniki nyamukuru mu nganda ni ingufu za DC zifite ingufu nyinshi. Kugeza ubu, ibinyabiziga n'ibirundo byombi byageze ku nini nini, kandi imbaraga z'uburyo DC iboneka byihuse ni 60-120KW. Kugirango urusheho kugabanya igihe cyo kwishyuza, hari ibyerekezo bibiri byiterambere mugihe kizaza. Imwe ni amashanyarazi menshi ya DC yihuta, naho ubundi ni voltage nini ya DC yihuta. Ihame nugukomeza kongera ingufu zumuriro mukongera amashanyarazi cyangwa kongera voltage.
Ingorabahizi yubuhanga bwihuse bwo kwishyuza iri mubisabwa byo gukwirakwiza ubushyuhe bwinshi. Tesla nisosiyete ihagarariye DC-yihuta yo kwishyuza byihuse. Bitewe numuyoboro mwinshi utanga amashanyarazi murwego rwo hambere, Tesla yahisemo kugumya guhuza ibinyabiziga bya voltage yimodoka kandi ikoresha DC-nini cyane kugirango igere kumashanyarazi byihuse. Tesla ya V3 supercharger ifite umusaruro mwinshi hafi ya 520A nimbaraga nini zo kwishyuza 250kW. Nyamara, ibibi byubuhanga bugezweho bwihuse bwo kwishyuza ni uko bishobora kugera gusa kumashanyarazi ntarengwa mubihe 10-30% bya SOC. Iyo kwishyuza kuri 30-90% SOC, ugereranije na Tesla V2 yishyuza ikirundo (umusaruro mwinshi uriho 330A, ingufu ntarengwa 150kW), ibyiza ntabwo bigaragara. Mubyongeyeho, tekinoroji igezweho ntishobora guhaza ibikenewe kwishyurwa 4C. Kugirango ugere kuri 4C yishyurwa, ubwubatsi bwa voltage ndende buracyakenewe kwakirwa. Kubera ko ibicuruzwa bitanga ubushyuhe bwinshi mugihe cyo kwishyuza cyane, kubera gutekereza ku mutekano wa batiri, igishushanyo mbonera cyacyo n’ikoranabuhanga bisaba gukwirakwiza ubushyuhe bukabije cyane, ibyo bikaba bizanatuma ibiciro byiyongera byanze bikunze.
